bpython 功能强大的Python shell
Python是一个非常实用、流行的解释型编程语言，其优势之一就是可以借助其交互的shell进行探索式地编程。你可以试着输入一些代码，然后马上获得解释器的反馈，而不必专门写一个脚本。但是Python自带的shell也有一些局限性，例如无法自动补全、不能高亮语法等。
好在强大的Python对默认shell进行了扩展，开发了许多漂亮的Python shell。每一个都提供了一个极好的交互性的Python 体验。今天我就为大家介绍其中较为优秀的一款 — bpython。
bpython简介
bpython是一个不错的Python解释器的界面，开发者的目的是提供给用户所有的内置功能，很像现在的IDE（集成开发环境），但是将这些功能封装在在一个简单，轻量级的包里，可以在终端窗口里面运行。
bpython并不追求创造任何新的或者开创性的东西。相反，它聚集了一些简洁的理念，关注于实用性和操作性。
如何安装
bpython最新版本是0.15。有四种安装方式：
- 官网下载最新版本的tarball：http://bpython-interpreter.org/releases/
- 克隆bpython的Git仓库：git clone https://github.com/bpython/bpython/
- 通过pip安装：pip install bpython
- 通过系统自带的包管理器：apt-get install bpython
想让bpython正常运行的话，还需要安装以下依赖包：
Pygments requests curtsies >= 0.1.18,
具体功能
功能十分丰富，具体包括：
- 内置的语法高亮 – 使用Pygments排版你敲出的代码，并合理配色
- 根据你的行为，显示自动补全的建议
- 为任何Python函数列出所期望的参数 – 可以显示你调用的任何函数的参数列表
- “Rewind”功能会调出内存里的最后一行代码并重新执行
- 可以将你输入的代码送到pastebin
- 可以将你输入的代码保存到一个文件
- 自动缩进
- 支持Python 3
类似的Python shell
除了bpython之外，还有IPython、ptpython和dreampie等三个类似的Python shell。
知道什么是bpython，它的安装方法，功能了吧，希望大家可以深入的进行了解。
